But chorus 12 speed is quiet as... really quiet as it is.
My sram force drivetrain, with the axs chain makes less noise than my all chorus 12 drivetrain ever did.
It must be in the ears, because I've heard a few Force drivetrains and there are even some videos on Youtube showing how loud and "grindy" it is

Could anyone comment on whether the Campag 12 spd cassette will work with a CK 11 speed frehub body, particularly whether the chain-catcher tabs on the largest sprocket will foul the spokes? Thanks very much

I have read in another thread that miche will come out with a 12 speed campy cassette. Any updates on that?
Camapagnolo asked miche to make one and they did. The 14-29t was used by a pro team in a race this year. Currently campag have just allowed 16-29t and 14-29t. I will order these but other ratios will become available in due course.

What race and team was that? This seems ridiculously short gearing for a pro race, except maybe on uphill TTs (but depending on the course, because if there's a flat section that could be a problem).

That is interesting that campagnolo does not allow miche to make other ratios like they do for 11 speed.

I swear Pogacar used that cassette on the 20th stage of the Tour. I cannot find where I read that.
That would make sense, if it was only for the climbing bike he used after the swap.

What would have me (finally) moving from Chorus 11 to Chorus 12 in a heartbeat would be:
12-13-14-15-16-17-19-21-23-26-29-32
Basically starting with the 11 speed 12-29 and adding a 32 instead of an 11 as Campy (strangely) chose to do.

That seems like a no-brainer.

52/12 and a 48/11 are nearly Identical gears, so those wanting the 52 or 53/12 top gear should consider the 48/32 crank.

12 speed Campy should be fully compatible with standard Campy free hubs that were in use in 9s 10s and 11s systems.
The new Super Record™ 12 Speed sprocket sets feature thinner sprockets, tighter spaces and space-saving dimensions that are the same as those of the 11 Speed sprockets
